The bottle is a great idea. It does have a few problems. The lid is too tight. Yes, I know, to keep from leaking. The lid is difficult to get off. So tight, where when it releases, you probably would sling the contents everywhere. Then in turn, you have to put it on the table and press it into the bottle. Also, the cork material is crumbling, putting small debris into the bottle. This is from it being too tight. I love the design and hope that they can improve on this. Sadly, I don't think I'll be able to use it.
